Lazy property with nosetter accessor remains uninitialized

[sashakboo]

In my project after upgrading from version 5.2 to 5.3 there is a problem with lazy properties that have nosetter.pascal-underscore accessor in their mapping.

• After accessing the property it remains uninitialized
• Each call to a property getter returns a new object

I have added tests which demonstrate the problem #3331

There is no such problem in version 5.2 #3332

Most likely caused by #1943

The 5.3.x+ lazy property implementation (#1943 and #1947) expects that both the getter and setter go through interception. And the following method must be called:

nhibernate-core/src/NHibernate/Intercept/AbstractFieldInterceptor.cs

Line 101 in 90d50c0

public object Intercept(object target, string fieldName, object value, bool setter)

.

However, with field accessor, no interception occurs. This means that lazy property handling is broken in multiple places for nosetter/field lazy property accessors. In addition to the added test, the existing CanMergeTransientWithLazyProperty is also broken. I suspect that fetching such properties in a query would not work either.

I took a quick look at how it is handled in Hibernate and it looks like they do not depend on interception in setter (at least for property initialization I see multiple attributeInitialized calls).

See no easy fix for it.
